Getting Started with EXS24

So here we have one of my favorite instruments in Logic. This is the EXS24 sampler. So a software sampler is a little bit different than a software synthesizer. A synthesizer generates its tones through oscillators. That's creating the basis of the sound. The sampler, on other hand, is based on audio recordings. Usually those audio recordings are referred to as samples. I'm going to have many samples that are tuned and grouped and mapped across the keyboard into a collection known as a sampler instrument. So the EXS24 can load and play back and edit and you can create sampler instruments.

The amazing thing about a sampler is because it is based on actual audio recordings, it's great at recreating realistic instruments like pianos, violins, and saxophone. Literally anything you can imagine that you can record you can make a sampler instrument out of. So let's take a look at the interface. So right here what we have is the Parameter window. That's actually this whole entire window here. The other main window that's not totally apparent at first is this Edit window. So this is known as the Instrument Editor, and here's where you do all the sample mapping.

So what you have is a whole bunch of zones. That's these down here. You can think of zones as containers, and in each container you're going to load an audio file. So there's a bunch of zones and those zones can be grouped together into groups, and then you can effect change on those groups. Also, you have velocity parameters here, so you can layer multiple zones in different velocity ranges, and so you can have depending how hard you're playing a note on the keyboard, trigger different samples. So lots of neat stuff, and we'll cover it all in really great detail.

So going back to our Parameter window for a moment, this is kind of similar to most of the synthesizers we've looked at. So you can see here is the filter. We've got the amplifier. Here's a modulation router, and then down here there's three LFOs and two envelopes. So the only thing is missing is an oscillator section. That's basically this area here. This is where we load in the sample instruments. And if I click here, I can load in a sampler instrument, and remember that's going to have all the audio files and samples that are mapped out across the keyboard, so that's what's going to be generating the sound, and then we shape it with the filter here, and it's a multimode filter, band pass, low pass and high pass.

And then we have a couple of global parameters up here. We have the voicing settings that we see in synthesizers: Legato, Mono, and Poly, and of course Unison mode. And we have some pitch parameters that have to do with Transpose and some other global parameters over here that have to do with velocity offsets and cross- fading between velocity layers. So we'll take a look at all that. So let's listen to an example. This is a musical example that has a couple of instances of EXS24 that are providing bass and some synthesis-sounding stuff and percussion so on and so forth.

So let's check it out, and then let's dig into EXS24. (music playing)
